Shell Scripting Lesson 6 - Working With Arrays

You Can define Arrays in Shell Scripting. In this tutorial, I am going to describe how to use arrays in Shell Scripting. Using Arrays are useful for store several Numbers,Integers etc.

Declaring Array

array_name[index]=value

See Below Example.


Example

TUTORIAL[0]="shell scripting"
TUTORIAL[1]="awk"
TUTORIAL[2]="sed"

You Can access single Element of an Array by using following Command

${array_name[index]}

See Below Example.

#!/bin/sh
TUTORIAL[0]="shell scripting"
TUTORIAL[1]="awk"
TUTORIAL[2]="sed"
echo "First Tutorial: ${TUTORIAL[0]}"
echo "Second Tutorial: ${TUTORIAL[1]}"

you can access all Elements of an Array by Using following Command.

${array_name[*]}
${array_name[@]}

See Below Example.

#!/bin/sh
TUTORIAL[0]="shell scripting"
TUTORIAL[1]="awk"
TUTORIAL[2]="sed"
echo "All Tutorial - Method 1: ${TUTORIAL[*]}"
echo "All Tutorial - Method 1: ${TUTORIAL[@]}"

See You Soon....
